最近开发app搞到历史查询，受腾讯qq的启发，搞一个具有时间轴效果的ui，看上去还可以，然后马上想到分享给小伙伴，，大家一起来看看，先上效果图吧

接下来就是代码了，axtivity的布局代码，很简单，就是一个listview

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <ListView     android:id="@+id/listview"    android:layout_width="fill_parent"    android:layout_height="wrap_content"/>    </LinearLayout>

下面就是activity.java这个了

package com.agbc.activity;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import com.agbc.adapter.TimelineAdapter;import com.agbc.listview.XListView;import com.example.agbc.R;import com.lidroid.xutils.ViewUtils;import com.lidroid.xutils.view.annotation.ViewInject;import android.os.Bundle;import android.support.v4.app.FragmentActivity;import android.widget.ListView;/** * 历史时间轴 * @author twj * */public class HistoryTaskActivity extends FragmentActivity{private XListView listView;List<String> data ;private TimelineAdapter timelineAdapter;@Overrideprotected void onCreate(Bundle arg0) {super.onCreate(arg0);setContentView(R.layout.activity_timeline);findViewById();listView.setDividerHeight(0);timelineAdapter=new TimelineAdapter(getDate(), this);listView.setAdapter(timelineAdapter);}private List<Map<String, Object>> getDate() {List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();Map<String, Object> map = new HashMap<String, Object>();map.put("year", "2014");map.put("month", "03/15");map.put("title", "这是第1行测试数据");list.add(map);map = new HashMap<String, Object>();map.put("year", "2014");map.put("month", "12/1");map.put("title", "这是第2行测试数据");list.add(map);map = new HashMap<String, Object>();map.put("year", "2013");map.put("month", "11/15");map.put("title", "这是第3行测试数据");list.add(map);map = new HashMap<String, Object>();map.put("year", "1998");map.put("month", "01/1");map.put("title", "这是第4行测试数据");list.add(map);return list;}private void findViewById() {listView=(XListView) findViewById(R.id.listview);}}

接下来就是适配器了，适配器其实也简单

package com.example.timelinetext.test;import java.util.List;import java.util.Map;import android.content.Context;import android.util.Log;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;public class TimelineAdapter extends BaseAdapter {private Context context;private List<Map<String, Object>> list;private LayoutInflater inflater;public TimelineAdapter(Context context, List<Map<String, Object>> list) {super();this.context = context;this.list = list;}@Overridepublic int getCount() {return list.size();}@Overridepublic Object getItem(int position) {return position;}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {ViewHolder viewHolder = null;inflater = LayoutInflater.from(parent.getContext());convertView = inflater.inflate(R.layout.adapter_timeline, null);viewHolder = new ViewHolder();viewHolder.year = (TextView) convertView.findViewById(R.id.year);viewHolder.month = (TextView) convertView.findViewById(R.id.month);viewHolder.title = (TextView) convertView.findViewById(R.id.title);String yearStr = list.get(position).get("year").toString();String monthStr = list.get(position).get("month").toString();String titleStr = list.get(position).get("title").toString();viewHolder.year.setText( yearStr);viewHolder.month.setText(monthStr);viewHolder.title.setText(titleStr);return convertView;}static class ViewHolder {public TextView year;public TextView month;public TextView title;}}

最后就是适配器布局代码了，其实效果就是在这里提现出来的

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"

 android:gravity="center" >        <TextView            android:id="@+id/year"            android:layout_width="wrap_content"            android:layout_height="wrap_content"

好吧！时间轴其实原理很简单的，就是几个控件，调调位置而已，不过在实际开发中可能要对时间轴上面的控件进行操作，这就是关于事件分发的机制了，哎，其实都是写烂的代码了，好了，这个天我要去研究tcp/ip通信了，
